  • Page 30: Figure 6 - Multimedia Conferencing Via The Gateway

    Integrating the L2W-323 Gateway into Your Network The following section gives you examples of how to integrate the L2W-323 Gateway into your network, depending on the intended application. The L2W-323 Gateway has two main applications in H.323 networks: multimedia conferencing and Voice over IP.

  • Page 31: Figure 7 - Voice Over Ip Communication Via Gateways

    !" Telecommuting Voice Over IP (VoIP) Application The L2W-323 Gateway allows H.320 terminals, ISDN and regular phones to exchange voice with other H.320 terminals, ISDN and regular phones over an IP network bypassing a long distance switched network, as illustrated by the following figure:...

  • Page 32: Figure 8 - Connecting More Than One L2W-323 Gateway Lan Port

    Overview Types of Connections The L2W-323 Gateway, which supports one LAN and up to four WAN connections, is scalable and can be easily adapted to fit your network needs. You can stack several Gateways one on top of the other to increase the number of WAN connections and available channels.

    L2W-323 Gateway and internal Gatekeeper operate. The L2W-323 in the H.323 Network The L2W-323 Gateway functions on the H.323 network as the translator between the IP LAN endpoints and other standard-compliant terminals on public circuit-switched networks.
  • Page 36 The WAN terminal determines the type of connection—voice or video. When a call originating on the WAN reaches the L2W-323 Gateway, the Gateway has to forward it to a LAN endpoint. This is achieved through one of the several incoming call routing methods the Gateway supports.
  • Page 37 The Gateway operates with the internal IVR or an external RADVision IVR on a PC. When an incoming call activates the IVR system, it initiates an interactive session with the caller.
  • Page 38 Overview Default Extension The default extensions can be any endpoint on the LAN and all calls not routed via one of the above incoming call routing methods, are forwarded to this endpoint. Default extensions can be defined per WAN port. Incoming Call Routing Logic The Gateway routes an incoming call from the WAN according to the routing methods enabled for the WAN port during configuration, following this order of priority:...

  • Page 41 Gateway Registration The L2W-323 Gateway supports the RAS protocol and can dynamically register with the Gatekeeper. It is recommended not to predefine properties for the L2W-323 Gateway as this may prevent the Gateway from functioning properly. Endpoints that do not support the RAS protocol can make calls even if they are not predefined.

  • Page 42: Service Providers

    Overview Predefined Endpoint Registration Predefined H.323 endpoints that do not support the RAS protocol are permanently registered with the Gatekeeper. This does not mean the endpoint is necessarily online. You can define these types of endpoints as Online Always. The Online Always parameter indicates to the Gatekeeper that the endpoint is ready to receive calls.
  • Page 43 Understanding the Internal Gatekeeper Terminals and Group Hunting Terminals can also register with the Gatekeeper as service providers. This occurs when you define a service in the Gatekeeper and then define that service prefix for the terminal as an additional phone number. When the terminal registers with the Gatekeeper, the Gatekeeper finds recognizes the additional phone number as a service.

  • Page 44: Working With Several Gatekeepers

    Overview Service Access Control You can control the access to services by defining them as Public, Default or both. The availability of a service to an endpoint depends on the origin of the endpoint requesting the call and the type of endpoint registration. Public services are available to: !"...

  • Page 45: Optimizing Call Routing On The H.323 Network

    Understanding the Internal Gatekeeper Distance between Neighbor Gatekeepers You can define a distance between zones in a network to give you more management control over endpoint calling privileges and restrictions. The distance is a logical range assigned between zones in the network. The distance between zones is defined by the Neighbor Distance parameter.

  • Page 47: Call Transfer

    Call Transfer Call Transfer is a proprietary RADVision call transfer mechanism by which the Gateway transfers a call from one LAN endpoint to another. The L2W-323 Gateway supports Call Transfer when operating with a RADVision or third-party gatekeeper, for incoming calls (from a phone on the WAN) to a LAN endpoint.

  • Page 210 Troubleshooting the L2W-323 Gateway running. The Gatekeeper does not identify that these terminals are disconnected from the LAN and tries to forward calls to them. A call forwarded to such a terminal is disconnected. If none of the online endpoints registered to the Gatekeeper with phone numbers assigned to the BRI line to which the Gateway is connected, and one of the phone numbers is dialed, the call is disconnected.
  • Page 211 Problems Using the L2W-323 Gateway Note: Some endpoints such as Microsoft NetMeeting version 2.x do not support the RAS protocol and cannot dynamically register with the Gatekeeper. In this case you have to predefine the endpoint in the Gatekeeper Zone Definition table and define it as “Online Always.”...
